Asterisk with mISDNV2 using chan_lcr
Setting up ISDN Support in Asterisk using chan_lcr module
In this both LCR and Asterisk should be running,LCR handles all the ISDN related stuffs signaling and transmits to asterisk using
socket to chan_lcr.
A.Prepare fedora installation (Fedora 11 -2.6.30)
1. Install following packages
Yum install kernel,gcc,patch,autconf,vim,samba,openssh,newt-devel,gtk2-devel,gcc-c++,libtermcap-devel
2. Remove already exisiting misdn_core ,and hfc drivers (hfcpic.ko)
Delete
/lib/modules/2.6.30.10-105.2.23.fc11.i586/kernel/drivers/isdn
B.Installatin of mISDN,mISDNuser and LCR
1. Dowload all the packages from LCR site
http://isdn.eversberg.eu/download/lcr-1.7/mISDN-20100525.tar.gz
http://isdn.eversberg.eu/download/lcr-1.7/mISDNuser-20100525.tar.gz
http://isdn.eversberg.eu/download/lcr-1.7/lcr-20100601.tar.gz
2. Install Misdn Core
- ./configure
- Copy mISDN.cfg.default to standalone/mISDN.cfg and edit it for you needs
Comment these
#CONFIG_MISDN_HFCMULTI_8xx
#CONFIG_MISDN_HFCUSB
#CONFIG_MISDN_XHFC
#CONFIG_MISDN_L1LOOP
#CONFIG_MISDN_AVMFRITZ
#CONFIG_MISDN_SPEEDFAX
#CONFIG_MISDN_INFINEON
#CONFIG_MISDN_W6692
#CONFIG_MISDN_NETJET
#CONFIG_MISDN_IPAC
#CONFIG_MISDN_ISAR
- make modules
- make modules-install
- insert the kernel modules created :
a.insmod ./standalone/drivers/isdn/mISDN/mISDN_core.ko ( dmesg shows Modular ISDN core version 1.1.21 NET: Registered protocol family 34)
b.insmod ./standalone/drivers/isdn/mISDN/mISDN_dsp.ko
c.insmod ./standalone/drivers/isdn/hardware/mISDN/hfcpci.ko
(Note :
dmesg shows
hfcpci 0000:01:07.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
mISDN_hfcpci: found adapter CCD/Billion/Asuscom 2BD0 at 0000:01:07.0
mISDN: HFC-PCI driver 2.0
HFC-PCI: defined at mem 0xe1beac00 fifo 0xd89c0000(0x189c0000) IRQ 16 HZ 1000
HFC 1 cards installed
)
3.Install misdn user
· cd mISDNuser
· (2.6.32.2 use --with-AF_ISDN=34 (e.g. dmesg | grep family))
./configure --with-AF_ISDN=34
· make
· make install
ln -s /home/alok/ISDN/mISDNuser/lib/.libs/libmisdn.so /usr/lib/libmisdn.so.0
ln -s /home/alok/ISDN/mISDNuser/suppserv/.libs/libsuppserv.so /usr/lib/libsuppserv.so.0
4.Install LCR
Before installing LCR ensure asterisk is compiled,
cp -r asterisk-1.4.34/include/asterisk /usr/include/
./configure –with-asterisk
make
make install
Copying chan_lcr to asterisk
This creates a channel driver to interact with LCR - “chan_lcr” copy these channel driver so to asterisk module folder
cp chan_lcr.so /usr/lib/asterisk/modules/
Run Programs
1.Start LCR
2.Start Asterisk now asterisk listerning to LCR using socket through chan_lcr
Like asterisk configuration files sip.conf ,extensions.conf LCR to has configuration
most important is routing.conf and interface.conf.
Below is sample conf files to make SIP <->ISDN.
Generic Dialplans
Change asterisk conf files
| Extensions.conf [default] exten => 1000,1,Dial(SIP/1000) exten => 2000,1,Dial(SIP/2000) include = asterisk_to_misdn
;directly called from lcr(ISDN to SIP) [asterisk_from_misdn] exten=>_X.,1,Dial(SIP/${EXTEN})
;SIP to ISDN [asterisk_to_misdn] exten => 8000,1,Dial(LCR/misdn/8000) |
Dialing 8000 with Dial Phone connect to ISND port.
Change LCR conf files
| interface.conf [misdn] portnum 0 nt msn 8000 routing.conf [main] : remote application=asterisk context=asterisk_from_misdn |
Some other Dialplan notes
ISDN to SIP
Interface.conf
[misdnintern]
portnum 0
nt
msn 400 ;this is called id of ISDN phone
>>Eg.1
Rounting.conf
[main]
dialing=5678 : remote application=asterisk context=extern_context exten=5
extensions.conf
[extern_context]
exten=>5,1,Dial(SIP/1000)
Note:here dialing 5678 from ISDN Phone will call extern_context and send exten=5 so it will dial 1000
>>Eg.2
Generic calling
Rounting.conf
[main]
: remote application=asterisk context=extern_context
extensions.conf
[extern_context]
exten=>_X.,1,Dial(SIP/${EXTEN})Note:Dialing any number from ISDN will call extern_context in extensions.conf and will pass extension whatever we have dialed.i.e 1000 from ISDN phone will dial SIP/1000.
>>Eg.3
Routing through interface
Rounting.conf
[main]
interface=misdnintern : remote application=asterisk context=extern_context
extensions.conf
[extern_context]
exten=>_X.,1,Dial(SIP/${EXTEN})
